T all whom it may concern:

Be it known that we, THOMAS J. Fncnnx and Gnoncn O. Lnoronn, citizens of the United States, and residents of Philadelphia, county of Philadelphia, State of Pennsylvania, have invented certain Improvements in Vises, of which the following is a specification.

One object of our'invention is to make a vise which can be used either as a bench vise or as a clamp on a bed of a machine tool, such as adrill.

A further object of the invention is to design the vise so that it can be turned on its support to any position -desired and firmly looked after ad ustment.

A still further object of the invention is to make the vise substantial, with a broad bearing surface so that it will readily resist the strains to which it is sub ected.

In the accompanying drawings F1gure 1, is a perspective view of our improved vise, showing it mounted on a swivel sup port; Fig. 2, is a longitudinal sectional view; Fig. 3, is a transverse sectional view on the line ma, Fig. 2; Fig. 4:, is a detached perspective view of the swivel portion of the base; Fig. 5, is a detached perspective view of the fixed jaw; Fig. 5, is a detached perspective view of one of the bars; Fig. 6, is a detached perspective view of the swivel plate secured to the movable portion of the base; Fig. 7, is a perspective view of the arm by which the screw is turned; and Fig. 8, is a view illustrating a modification of the invention.

Referrin to the drawings, 1' is the base having a ange in which are the openings for the screws by which it is secured to a work-bench or other support. This base has a circular opening with a tapered annular wall, and mounted in the o enin is a disk 2, Fig. 6. The periphery of the isk is beveled to fit the tapered opening in the base 1.

3 is the swiveled member of the base section which rests on the fixedbase 1 and has a recess 4 out in its underside to receive the projection 5 of the disk 2. Said disk 2 has I a central threaded opening 6 and the section 3 has a plain opening which extends into a' the section 3 and the disk 2 to turn in the base 1 to any position desired. We preferably provide a handle 10, shaped as shown in Fig. 7 which can be detached from the head of the bolt 8, but we prefer to confine it to the head by a screw 11 which is-passed through the section 3 and extends over the end of the handle. By this arrangement the handle can be detached from the screw.

The swivel section 3 of the base has a rib *at each side of the opening 7 which forms a guideway for the vise proper. The extension 12 of one rib of the section 3 is undercut at 13 to fit the beveled end 14: of the fixed jaw 15, and at the opposite side is an extension 16 having a set screw 18 which bears against the beveled portion 17 at the rear of the fixed jaw 15. The base section 3 has an opening 19 at one side, as clearly shown in F i s. 3 and 4, to allow freedom of movement oi the handle 10.

The fixed jaw 15 has an extension 20 forming the jaw proper and at the rear of the extension is an opening 21 for the end 23 of the main screw. The end 23 is reduced at 24 toform an annular groove to receive the confining screw 25, which extends up through the jaw 15, as clearly illustrated in Figs. 2 and 3. The fixed jaw 15 is grooved at '35, at each side, to receive the bars 36, Fig. 5, and these bars when once in place are held to the fixed jaw by the head of the screw 25 which enters the notches 36 in the bars.

The sliding jaw 26 has an extended base portion 27 fiormed of two integral members spaced apart to pass on each side of the body of theffixed jaw 15; each member has a shoulder which rests on the bar- 36 at each side of the fixed jaw. Thus the sliding jaw is held between the bars and the portion 29 of the fixed jaw.

At the forward end of the movable jaw 26 is the main jaw 30 corresponding to the main portion 20 of the fixed jaw, and at the rear of the movable jaw is a bearing 31 having a screw threaded opening through which extends the screw 22. On the end of this screw is a head 32 through which extends a turning bar 33 of the ordinary type.

When the vise is mounted on the swivable-on the fixed jaw and can be moved to eled base, as in Figs. 1, 2 and 3, the jaw is fixed to the base and the jaw 26 is movsimilar types of vises. By backing ofl the bolt 8 the swivel section can be turned on the fixed portion of the base to any degree desired, and by tightening the bolt it is rigidly held in position.

When it is desired to detach the vise proper from the base, all that is necessary is to back off the clamp screw 18, after which the two jaws, with the main screw, can be removed from the base, and as the underside of the extended portion of the movable jaw is perfectly fiat, as well as each side, the vise proper can be mounted on any surface plate, or on the plate of any machine, such as a drill, in order to clamp the work in the proper position. The fixed jaw then becomes the movable jaw and can be moved to and from the portion 30 of the jaw 26.

Instead of the construction illustrated in Figs. 2 and 6, the disk 2* may have the pins 37 which extend into the openings 38 in the swivel section 3, without departing from the essential features of the invention.

\Ve claim 1. The combination in a combined swivel and machine vise, of two jaws, one arranged to slide with respect to the other, one jaw having an extension flat on the under side, the other jaw having a body portion located in the extension but less in depth than said extension; a swivel section to which the body portion of one jaw is detachably secured so that one jaw is the fixed jaw when the vise is arranged as a-swivel vise and the ether jaw is a fixed jaw when the vise is detached from the swivel and is acting as a.

machine vise.

2. The combination in a vise, of a swivel member having two vertical extensions, one extension being under cut and the other having a horizontal threaded opening therethrough; afixed jaw having a body portion located between the two extensions of the swivel section, one end fitting the under cut 3. The combination in a vise, oftwo jaws,

portion formed by twointegral members one of said jaws having an extended base spaced apart, said members being under out longitudinally, the other jaw having a body portion extending into the space between the two members, the body portion being slottedlongitudinally at each side to aline with the under cut portion; a bar located in each slot and extendinginto theunder cut portion of the two members; and means for holding the bars against longitudinal movement, the bars retaining the jaws in alinement.

4. The combination in a vise, of a fixed base having a circular undercut opening therein; a disk mounted in the opening; a swiveled section mounted on the fixed base and arranged to turn with the disk, said disk having a screw threaded opening therein; a bolt extending through the opening in the swiveled section and into the threaded opening in the base, the swiveled section being slotted at one side; a handle extending through the slot and engaging the head of the bolt; and apin extending over the handle at one side of the bolt so as to prevent accidental removal of the handle without backing oflthe pin.

5. The combination in a vise, of two jaws, one movable in respect to the other, one jaw having a groove at each side; a notched bar located in each groove; and a screw in the grooved jaw entering the notches in the bars, the other jaw having a-shouldered b'ase portion extending over the bars and under portions of the other jaw.

6. The combination in a vise, of two ]3WS,,

one movable in respect to the other, one'jawhaving a body portion and an extended base, u

the other jaw having a bodyportion extend s7 ing over the base and'a depending portion extending through a slot in the base; a screw mounted in the projection of the base and; located in the opening in the other jaw, the latter jaw being slotted at each side; a-' notched bar mounted in each slot and'fextending under shoulders formed in the base of the other jaw; and a screw arranged to} secure therbars in the slots and themain' screw to its jaw. j In testimony whereof, we have .signed' names to this specification, in the presence I two subscribing witnesses. v H V.
